A-D would all be awesome hunts. Just draw the tag. The draw odds tell you everything you need to know about them. The only one to be wary of is B, which is all wilderness. It's rugged, awesome country, but is physically demanding.
I was hunting down there a few years back and met a guy who was flabbergasted that 16B was all wilderness and complained that he had no idea until he got down there and couldn't find a road into the unit. He was headed home because he couldn't find an easy way to hunt the unit and didn't want to miss the Broncos game. He then handed me a business card for his outfitting business and encouraged me to apply for a guided elk hunt with him the next year. Ha!!
